What is the purpose of a joggle in construction?

A joggle in construction serves a critical function by creating an offset or indentation in the sheet metal. This design feature allows for the necessary clearance for various components during assembly or operation. For example, when connecting two pieces of metal or when accommodating the shape of an adjoining part, a joggle ensures that there is sufficient space to avoid interference that could lead to structural issues or hinder functionality.

The primary purpose is practical: it addresses potential fitment problems that may arise from the complexity of assemblies, especially in applications like aircraft where precision is key. The other options, while related to construction concepts, do not accurately reflect the specific role of a joggle. Providing insulation, increasing tensile strength, or reducing weight are not direct outcomes of integrating a joggle; hence, they do not represent its main purpose.
